We look at the division of 77910779 by 223 
We're looking to find how many times 223 goes into 77910779.

Moving on to step 1:
When dividing 7 by 223, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 223

Step 2:
The number 223 fits into 77 0 times, leaving a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Bring next digit (9) of the dividend behind the 77 and repeat the process: 779 / 223

Advancing to step 3:
223 goes into 779 3 times with a remainder of 110.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 669 from 779 leaves us with 110.
Take the next digit (1) from the dividend and append it to 110, then repeat: 1101 / 223

Let's proceed to step 4:
1101 divided by 223 is 4 with a remainder of 209.
Write down 4 as next digit of the result. 
Result so far: 34.0
If we subtract 892 from 1101, we get 209.
Append the next digit (0) from the dividend to 209 and continue with: 2090 / 223

Advancing to step 5:
If we divide 2090 by 223, we get 9 and a remainder of 83.
Record the quotient 9 as the next digit in the result. 
Result so far: 349.0
Subtracting 2007 from 2090 leaves us with 83.
Take the next digit (7) from the dividend and append it to 83, then repeat: 837 / 223

Advancing to step 6:
The number 223 fits into 837 3 times, leaving a remainder of 168.
The next digit of our result is 3. 
Result so far: 3493.0
If we take 669 away from 837, we end up with 168.
Append the next digit (7) from the dividend to 168 and continue with: 1687 / 223

Going ahead to step 7:
223 goes into 1687 7 times with a remainder of 126.
Write down 7 as next digit of the result. 
Result so far: 34937.0
If we take 1561 away from 1687, we end up with 126.
Bring next digit (9) of the dividend behind the 126 and repeat the process: 1269 / 223

On to step 8:
When dividing 1269 by 223, we get 5 with a remainder of 154.
Write down 5 as next digit of the result. 
Result so far: 349375.0
Subtracting 1115 from 1269 leaves us with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Moving on to step 9:
223 goes into 1540 6 times with a remainder of 202.
Put 6 as the next digit of the answer. 
Result so far: 349375.6
Deduct 1338 from 1540 and we're left with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Moving on to step 10:
When dividing 2020 by 223, we get 9 with a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 349375.69
If we take 2007 away from 2020, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 11:
The number 223 fits into 130 0 times, leaving a remainder of 130.
Write down 0 as next digit of the result. 
Result so far: 349375.69
Subtracting 0 from 130 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 12:
1300 divided by 223 is 5 with a remainder of 185.
Write down 5 as next digit of the result. 
Result so far: 349375.6905
Subtract 1115 from 1300 to get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Let's proceed to step 13:
When dividing 1850 by 223, we get 8 with a remainder of 66.
Write down 8 as next digit of the result. 
Result so far: 349375.69058
Deduct 1784 from 1850 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 14:
223 goes into 660 2 times with a remainder of 214.
The next digit of our result is 2. 
Result so far: 349375.690582
The remainder is 214 after subtracting 446 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

On to step 15:
The number 223 fits into 2140 9 times, leaving a remainder of 133.
Write down 9 as next digit of the result. 
Result so far: 349375.6905829
The remainder is 133 after subtracting 2007 from 2140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

On to step 16:
If we divide 1330 by 223, we get 5 and a remainder of 215.
The next digit of our result is 5. 
Result so far: 349375.69058295
Deduct 1115 from 1330 and we're left with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

After the division, we end up with 349375.69058295 and a remainder of 2.15e-07.
